The find­ings of an in­ves­ti­ga­tion were an­nounced by the Ha­mas mil­i­tary wing, Qas­sam Brigades, in a pre­re­corded TV state­ment.

Ha­mas pre­sented surveil­lance footage and pho­tos to back up its claims.

Ha­mas thwarted an at­tempt to “plant spy­ing de­vices in the Gaza Strip,” a Qas­sam spokesman said in the state­ment.

Is­rael’s mil­i­tary has not re­leased de­tails about the op­er­a­tion, which went awry Nov. 11, lead­ing to the heav­i­est round of cross­bor­der fire, in­clud­ing Ha­mas rock­ets and Is­raeli airstrikes, since a 2014 war be­tween the two sides.
